--- Comment #7 from Ruben Van Boxem <vanboxem.ruben at gmail dot com> 2011-09-19 19:28:48 UTC --- I'm still experiencing the same behavior. I don't think the darwinx toolchain has the problems you say? Why do you think it uses a Darwin9 system framework and headers? It has GCC 4.2.1 and the Mac OS X 10.5 SDK, which are all pretty Darwin10 as far as I can see. Something changed in 4.6 vs 4.7. I have sys/malloc.h , objc/malloc.h, and malloc/malloc.h. Somehow, HAVE_MALLOC_H is being wrongfully defined to 1 when it should be 0. auto-host.h has the define commented out. auto-build.h has it defined. These are the same for GCC 4.6. So the problem must lie elsewhere... I noticed the gengtype-lex.o object file is build with i686-apple-darwin10-gcc for GCC 4.7, and (Linux) gcc for GCC 4.6. This cannot be intended behavior.
